Products

HVR Pentagon Anti-Condensation heaters have been designed for use in switch and control gear cubicles, where a low wattage heater is required to prevent condensation.

HVR Pentagon Dynamic Braking Resistors are supplied in a high quality heavy duty power resistor enclosure (IP20), manufactured from Zinc plated steel with a powder coated finish.

The HVR Silico resistors have high power dissipation and high energy absorption. They are manufactured mainly as rods and tubes with varying sizes. The Silico Resistors may be connected in series or parallel for various fields of application.

Incorporating our Ceramic Carbon Resistor Technology, HVR Earthing Sticks have been developed specifically for use in High Voltage, High Energy Discharge Applications where operator safety is the prime concern.

HVR's range of High Voltage Resistors for Compact Circuitry are manufactured from a carefully selected mixture of clays, alumina and carbon. After blending, the material is pressed to the required shape and then fired, in a controlled atmosphere, at high temperature.

With the capability of sustaining energies ranging from Joules to Mega-Joules, at frequencies up to Mega-Hz, HVR Linear Disc Resistors can be used in even the most demanding applications such as electrical transmission, traction, AC/DC drives, pulse power, dummy loads, induction heating and pulse forming networks.

HVR's range of Plug Pill Resistors are designed for use in spark plugs as suppressors. These resistors are available in a variety of geometries and have a high voltage withsatnd and high surge energy rating.

HVR Pentagon high quality heavy duty power resistor enclosures (IP20) are manufactured from Zinc plated steel and have a powder coated finish. Typical uses include Dynamic Braking, Motor Starting and Load Banks.

Ceramic Carbon Resistors can be offered separately, in matched sets with respect to Resistance Value, or pre-assembled for ease of installation. Resistor Discs can also be supplied in stacks, marked and numbered for optimum flatness and parallelism.

HVR Rod and Tube Resistors are manufactured from a carefully selected mixture of clays, alumina and carbon. After blending, the material is extruded into the required shape and then fired, in a controlled atmosphere, at high temperature

.

The RT / RL series of non inductive, ceramic composite resistors are ideal for circuitry associated with surges, high peak power or high energy, replacing carbon composition resistors which can be difficult to source.

The HVR SiC varistors have good voltage dependences and high energy absorption. They are manufactured mainly as discs with varying sizes, as the required electric values are most easily obtained with these geometric dimensions.

The SR Series of Surge Resistors for PCB mounting are compact in size and with high surge energy rating are designed for many power electronics applications such as soft starting the DC link capacitors in switch mode power supplies.

The Stud Mounted Range offers a compact, cost-effective solution for use in high energy charge and discharge applications such as dynamic braking, soft start and capacitor charge / discharge.

Thermostats include the RTR-E 3000 & RTR-E 6000 Series.

These successors to the 'Europa' range have been redeveloped to give an attractive modern design which incorporates proven bi-metal technology.

They are available with a wide range of variations.

HVR Pentagon Open Wire Wound Resistors are close wound with oxidised resistance wire and each resistor is fitted with an adjustable tapping clip as standard.
